Orgasm (Hers)

new to this site and a first time poster (but really enjoying what I've read so far, very honest and refreshing).

Anyway, to topic. I'm 52 and separated for almost three years. I've had a girlfriend of the same age for most of my separation (I never played away when married). Our lovelife is great, very passionate and spontaneous and I really enjoy being intimate with her. I love just lying in bed with her, holding her, talking to her.

However, though she has an orgasm fairly easily during lovemaking (by tongue, fingers, intercourse), SHE ONLY EVER HAS ONE. She says she's quite happy with this and I guess she must be. However, mixed messages here folks. I'm a simple bloke, and my reading of as much work on the subject as I can tends to suggest the more orgasms a woman can have the better. Or have I got it totally wrong?

So, comments please, does anyone have a view on this? I'll say here that it doesn't particularly worry me, though if I could give her more pleasure I'd love to be able to.

And, apologies if this has been discussed before. I hope it hasn't been a big yawn reading this far.
